[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-Figure 7 In this embodiment, a rotary punching device for punching the edge of a refrigerator liner includes a bracket 1, a panel 11 is symmetrically arranged on the top of the bracket 1, and the top of the panel 11 is symmetrically fixedly connected to a limiting column 17, and a refrigerator liner 10 is placed on the limiting column 17. A cylinder 4 is fixedly connected to one side of the bottom end of the panel 11, and an active rack 24 is fixedly connected to the output end of the cylinder 4. A punching gear 22 is rotatably connected to the top of the panel 11 on one side of the active rack 24, and the punching gear 22 is meshed with the active rack 24. The bottom end of the punching gear 22 is A punching knife 23 is fixedly connected to one side of the panel 11, a mounting frame 12 is fixedly connected to the top of the panel 11, a driven rack 14 connected to the driving rack 24 is slidably connected through the mounting frame 12, a driving gear 13 is rotatably connected to the top of the mounting frame 12 on one side of the driven rack 14, the driving gear 13 is meshed with the driven rack 14, a driven gear 21 is fixedly connected to the inner side of the driving gear 13, a transverse rack 15 is meshed below the driven gear 21, and a side of the transverse rack 15 close to the refrigerator inner tank 10 is fixedly connected to a limiting plate 9.

[0032] like Figure 1-Figure 3 and Figure 5 In this embodiment, both sides of the bracket 1 are slidably connected with a pressure plate 6, and a fixing bolt 5 is threadedly connected at the middle position of the pressure plate 6. The bottom end of the pressure plate 6 is evenly fixedly connected with a clamping rod 20, and the top of the panel 11 below the clamping rod 20 is evenly opened with an adjustment hole 19. The pressure plate 6 is lifted and fixed by loosening the fixing bolt 5, thereby canceling the limit on the panel 11. At this time, the panel 11 can be pushed to the desired position, and then the pressure plate 6 is pressed down so that the clamping rod 20 is stuck in the corresponding adjustment hole 19, and finally the position of the panel 11 is adjusted to ensure that the position of the subsequent punching knife 23 matches the position of the two corners of the refrigerator liner 10.

[0033] like Figure 3 and Figure 4 In this embodiment, a slide groove 18 is provided at the top of the bracket 1, and the panel 11 is slidably connected inside the slide groove 18 to facilitate stable adjustment of the position of the panel 11.

[0034] like Figure 1 , Figure 2 and Figure 6 The limiting plate 9 in this embodiment is L-shaped, and the top of the inner part of the limiting plate 9 is flush with the top of the refrigerator liner 10, so that the limiting plate 9 can press the refrigerator liner 10 to limit the position.

[0035] like Figure 1 In this embodiment, the top of the panel 11 outside the active rack 24 is fixedly connected to the lower shield 7, and the top of the mounting frame 12 is fixedly connected to the upper shield 8. The key transmission parts are protected by the lower shield 7 and the upper shield 8 to avoid injuries caused by accidental contact.

[0036] like Figure 2 and Figure 6 In this embodiment, the diameter of the driving gear 13 is twice the diameter of the driven gear 21. When the driving gear 13 rotates one circle, it can drive the driven gear 21 to rotate two circles, so that when it is not punched, it can drive the limit plate 9 to press the refrigerator liner 10 to limit.

[0037] like Figure 1 , Figure 2 and Figure 6 In this embodiment, a slide is fixedly connected to the top of the mounting frame 12 below the transverse rack 15, and the transverse rack 15 is slidably connected on the slide to ensure the stable movement of the transverse rack 15.

[0038] like Figure 1-Figure 3 In this embodiment, the top end of the limiting column 17 is protruding, and the top end shape of the limiting column 17 matches the internal shape of the refrigerator liner 10, so as to facilitate the lateral limitation of the refrigerator liner 10.

[0039] like Figure 3 In this embodiment, the top of the panel 11 below the punching knife 23 is fixedly connected with a punching frame 16, and a through hole matching the punching knife 23 is opened in the middle position of the punching frame 16 to facilitate the discharge of the punched waste.

[0040] like Figure 1-Figure 4 The through hole on the punching frame 16 in this embodiment passes through the bottom end of the panel 11, and the bottom end of the bracket 1 below the punching frame 16 is fixedly connected to the guide frame 2, and the inside of the guide frame 2 is slidably connected to the collecting box 3. The waste after punching will fall from the middle through hole of the punching frame 16 and finally be collected in the collecting box 3. After a certain period of time, the collecting box 3 can be pulled out for cleaning, thereby realizing convenient collection and cleaning of the waste.

[0041] It can be understood that the rotary punching device used for punching the edge of the refrigerator liner can adjust the position of the panel 11 to adapt to the punching of refrigerator liners 10 of different specifications, and at the same time change the traditional up and down punching to rotary punching, thereby reducing the stroke required for punching, facilitating the taking and placing of the refrigerator liner 10, and at the same time, during the punching process, the refrigerator liner 10 can be synchronously driven to limit the position, thereby ensuring the stability of the punching, and finally the punching waste can be collected to ensure the cleanliness of the workbench.

[0042] The complete use steps and working principle of the present invention are as follows:

[0043] First, the refrigerator liner 10 is placed on the top of the limiting column 17 to form a lateral limit. When punching, the cylinder 4 drives the active rack 24 to move upward. Since the active rack 24 is meshed with the punching gear 22, the punching gear 22 is driven to rotate so that the punching knife 23 punches the two sides of the bottom end of the refrigerator liner 10. After the punching is completed, the active rack 24 descends to reset the punching gear 22. Such rotary punching greatly reduces the punching stroke. In the process of punching, the active rack 24 moves upward to drive the driven rack 14 to move synchronously. Since the driven rack 14 is meshed with the active gear 13, the active gear 13 is driven to rotate, thereby driving the driven gear 21 to rotate. Since the driven gear 21 is meshed with the transverse rack 15, the transverse rack 15 is driven to push the limiting plate 9 to press on the top of the refrigerator liner 10, forming a longitudinal limit to the refrigerator liner 10, thereby ensuring the stability of punching.

[0044] The waste after punching will fall from the middle through hole of the punching frame 16 and finally be collected inside the collection box 3. After a certain period of time, the collection box 3 can be pulled out for cleaning, thereby realizing convenient collection and cleaning of the waste;

[0045] When the specifications of the punched refrigerator liner 10 are different, the position of the limit column 17 can be adjusted, and the fixing bolt 5 can be loosened to lift and fix the pressure plate 6, thereby canceling the limit on the panel 11. At this time, the panel 11 can be pushed to the desired position, and then the pressure plate 6 is pressed down so that the clamping rod 20 is inserted into the corresponding adjustment hole 19, and finally the position of the panel 11 is adjusted to ensure that the position of the subsequent punching knife 23 matches the two corners of the refrigerator liner 10.

[0046] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. The present invention is limited only by the claims and their full scope and equivalents.
